Separation Anxiety in Horses

Signs of separation anxiety

Common signs include:

• Increased heart rate
• Reluctance to eat or drink
• Increased passing of droppings or urination
• Trembling
• Sweating
• Calling or neighing
• Box walking or fence walking
• Rearing, bucking or napping when ridden

Every horse reacts differently. Some may only show mild signs, such as watching or calling for a companion, while others can become so distressed that they pose a risk to themselves or those handling or riding them.

Horses with severe separation anxiety are often anxious even when they are not actually separated from their companion. They can remain constantly on edge and hyper-vigilant, making everyday management difficult. In some cases, the problem becomes so challenging that owners feel they have no option but to retire or rehome the horse.

What causes separation anxiety?

Horses are prey animals and have evolved to live in herds, where there is safety in numbers. Other herd members help detect danger and provide reassurance while horses rest or sleep. A horse on its own is naturally more vulnerable, so being isolated can be highly stressful.

Horses also form strong social bonds, with some developing particularly close attachments to one companion. In the wild, these relationships can last for many years.

Modern horse management is very different from a horse's natural lifestyle. Many horses spend time in individual stables or small turnout paddocks with limited physical contact with other horses. This prevents natural social behaviours such as mutual grooming, playing and close companionship.

It is also common for horses to move between different yards throughout their lives, making it difficult for them to establish long-term social bonds. Frequent changes in companions and routine can increase stress and leave some horses becoming overly dependent on a particular field mate.

Some horses have very little contact with other horses altogether. For these animals, being left alone can be extremely frightening. From the horse's perspective, isolation increases their vulnerability to predators, causing them to remain constantly alert. Horses that do not feel secure enough to lie down and sleep properly may even develop sleep deprivation, which can lead to further behavioural and welfare problems.

Can separation anxiety be improved?

In many cases, yes.

With appropriate management changes and a gradual retraining programme, most horses can become much more confident when separated from their companions. Even horses with severe separation anxiety often improve when given time, consistency and a sympathetic approach.

The aim is to help the horse develop confidence when alone and to create positive associations with short periods of separation.

A common misconception is that keeping horses isolated will prevent them from becoming attached to others. In reality, this often has the opposite effect. Horses deprived of social contact frequently become even more dependent when they finally do form a bond with another horse.

Step-by-step guide to improving separation anxiety

1. Start small

Begin by taking your horse away from their companion for only a few seconds before returning them. During this time, offer a small feed or some forage so they begin to associate separation with something positive.

Gradually increase both the distance and the length of time apart.

2. Build up gradually

Repeat the exercise regularly, increasing either the time or the distance by only a small amount each session. Only progress while your horse remains relaxed.

If they become anxious, return to an easier stage before gradually building up again.

3. Review your horse's management

Simple management changes can make a significant difference. Consider:

• Changing stable locations if possible.
• Introducing compatible field companions.
• Varying the order in which horses are turned out or brought in to avoid predictable routines that trigger anxiety.

4. Support pair-bonded horses

If your horse has formed a particularly strong attachment to one companion, introduce a calm, confident and well-socialised horse during training sessions to help build confidence with other companions.

Where another horse is not available, some horses may benefit from the company of another suitable species, such as a donkey, goat or sheep, although another horse is generally the preferred option.

5. Seek professional help

For more severe cases, it is advisable to work with a qualified equine behaviourist. They can assess your horse's individual needs and develop a structured training plan to achieve long-term improvements.

With patience, consistency and sympathetic handling, most horses can learn to cope far better with time away from their companions, making life safer and less stressful for both horse and owner.
